Description

Bis(Nonylphenyl) Adipate is a high-molecular-weight diester plasticizer derived from adipic acid and nonylphenol. This compound is valued for its excellent compatibility with a wide range of polymers, providing enhanced flexibility and low-temperature performance. It is primarily utilized in the formulation of specialty plastics, synthetic rubbers, and polymer systems where durability and processability are critical.

Application

• Primary plasticizer for PVC (polyvinyl chloride) and other vinyl polymers.
• Key component in synthetic rubber formulations to improve elasticity and cold resistance.
• Functional additive in adhesive and sealant systems to modify rheology and tack.
• Processing aid and internal lubricant in engineering plastics and polymer blends.
• Used in the production of wire and cable insulation and jacketing compounds.
• Plasticizer for coated fabrics and flexible polymeric films.
• Additive in printing inks and specialty coatings to enhance film properties.

Quality Control

Our Bis(Nonylphenyl) Adipate is manufactured under a strict quality management system. Each batch undergoes rigorous analytical testing to ensure it meets precise specifications for purity, color, and performance characteristics. A comprehensive Certificate of Analysis (COA) detailing assay, identity, and impurity profiles is available for every shipment to guarantee consistency and traceability.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, dry, well-ventilated area at room temperature (15-25°C). Keep away from strong bases, oxidizing agents, and incompatible organic solvents. As the product is easily oxidized, prolonged storage under an inert atmosphere (e.g., nitrogen) is recommended for optimal shelf life.
